'ro ALL WHoM 15|: MAY ooNoERN:

Be it known that I, ISAAC T. CRUM, of Chicago, in the county of Cook, and State of Illinois, have invented- I a new and useful Form for Bending Rims for Horse-Collars; and I do hereby declare that the following is a.

full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings and letters of reference marked thereon, making a part of this specification, in whch-V Figure 1 is a plan view of my form, showing the position of the rim bent aroundit.

Figure 2 is a longitudinal elevation of the form, showing the position of the rim when being taken o of .the same.

This invention relates to that in which blocks are used, having external formsito correspond with the internal shape whichthe wood when bent is to have; and its natnreconsists iu the use of a form, made the required .shape of the collar, and havingilanges projecting outward from the lowex` part of the for-m for the purpose of holding the rim in position on the same when being bent; and further, in providing a. standard, placed at a suitable distance fromV the top end of the form, for holding the rim on -the form when and after being bent. By this arrangement a very convenient device is provided `for bending rims for collars at small cost. When but little work is required to be done on the form, it may be made' of wood, with metallic flanges and standard, but cast iron will be found the cheapest in the end, as the steam from the rim will not softenit like wood.

A represents the form, which mayl be made either of wood or metal, and of such shape as Awill best suit the neck of the horse. D shows flanges, projecting outward from the block far enough to preventrthe rim from slipping oli' when being bent. When thc form A is made of wood the ianges can be secured to it by means of the nails a, but when made of cast iron they can be cast solid with the form. H shows the shank of the standard C rigidly attached to the under side of the top of the form A by'meaus of the screws ff. This shank and standard can also be east solid with the form A when it ismade of iron.

i Operation.

B represents the rim after being bent onthe form A. In order to bend the rim, one end, as seen ath, must be' put between the standard C and the form A, after whichthe opposite end of the rim', as seen at L, eau bc forced around the form, lapped over the end K, and secured between the form and standard, as seen at iig. 1. B, iig. 2, shows how the riin may be forced downward so asto be taken off from the block without opening the Having thus fully described my device, what I claim, and desire to secure by Letters Patent of the United States, is

The combination of the form A with the ilanges Dand standard C, substantially as set forth.
